AMELIA UBBELOHDE, OF CELLE, GERMANY.

APPARATUS FOR CLEANSING FIBROUS MATERIALS.

SPECIFICATION forming part Of Letters Patent N0. 659,87 9, dated October16, 1900.

Application filed April 12, 1900. Serial No. 12,519. (No model.)

To aZZ whom it may concern.-

Be itknown that I, AMELIA UBBELOHDE, a subject of the German Emperor,residing at Celle, Villa Wester Celle, Germany, have invented certainnew and useful Apparatus for Cleansing Fibrous Materials; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an apparatus for cleansing wool or other fibrousmaterials by means of which the smaller particles of dirt and dust areseparated from the longer fibers, which are then collected.

The apparatus consists of a box-like receptacle, the bottom of which isof a funnel shape and is covered by a sieve, over which works areciprocating stirring device and a chain bucket device arranged totravel through the receptacle.

The said apparatus is shown on the accompanying drawings, in which-Figure 1 shows a vertical longitudinal section; Fig. 2, a cross-sectionon lineA B, Fig. 3, which shows a plan view. Fig. dis a modified form ofthe stirring-blades g.

The box-like receptacle c has its bottom formed as two funnels I),provided with discharge-cocks c and covered by a sieve d, upon which isplaced the fibrous material to be cleansed, the water for this purposebeing admitted at the upper part of the receptacle through a pipe. (Notshown.) \Vithin the receptacle is a carriage f, running to and fro onrollers in guides e and carrying pendent stirring-blades g. On thecarriage are fixed two looped uprights h, with which is engaged a bar2', the ends of which are secured to endless cords or chains 7s,stretched over rollers Zon the shafts m. On the one shaft to are fixedtwo toothed wheels to, with which gear pinionsp, fixed on the shaft 0,the latter be ing driven by any suitable driving-gear, such as by fastand loose belt-pulleys, as shown.

An advantageous form of the stirringblades is shown in Fig. 4.

3 is a frame with vertical rods 2, Which therefore form a series ofvertical slits. In the middle of the stirring-blade the rods 2 do notreach the under end of the frame, but there a cross-piece l is placedwhich has no slits. Aside of the cross-piece i slits again are providedat 4.

Through the receptacle pass chain-buckets led over guide-rollersq,driven in any suitable manner and whose buckets T have a sievelike orperforated bottom. The chains of the chain-buckets have no buckets uponone part of their length, which corresponds about with the length of thereceptacle a.

The action of the apparatus is as follows: The fibers to be cleansed areintroduced, together with water, into the receptacle a, the parts of thechains having no buckets being at that time situated within receptacle aover the sieve d and the vertically adjustable stirring-blades 9 havingbeen moved by their handles .9 into their lowest position on thecarriage. The shaft 0 is then rotated, Whereby the cords or chains 76are made to travel, carrying with them the bar 2', which in its turncauses the loops h and carriage f to travel along first in one directionand then after bar 2' has passed round the pulleys l at the one end itpropels the carriage in the contrary direction, so that by this meansthe stirring-blades g have a corresponding toand-fro motion imparted tothem. In this motion the blades travel with notched parts i over thebucketless parts of the chains of the chain buckets, which parts, asabove stated, are at that time situated over the sieve and are withoutmotion. By the effectual stirring to which the fibers are by this meanssubjected the finer particles of dirt and dust are separated from thelonger fibers and fall through the sieve (Z into the funnels b,whencethey are discharged from time to time, together with the water, throughthe cooks c. The cleansing having thus been effected, the stirringapparatus is stopped and the chainbuckets are set in motion through thereceptacle a. To enable this to be done, the stirring-blades g requirefirst to be raised up by means of the handles 5 and to be secured intheir raised position by suitable means, such as by pins passed throughholes therein. The chain-buckets can then travel along underneath thestirring-blades, and in doing so they scoop up the cleansed'fibers,together with the water, and carry the same up and away out of theapparatus, the water draining off through the sieve-bottoms and fallinginto the receptacle a, again. On passing over the upper right-handguide-rollers the buckets will have their position reversed, so that thefiber falls out of them, after which they pass down into the receptacleagain until all the cleansed fibers have been removed.

At the one side of the receptacle a is provided an opening 21), which isclosed bya valve or slide '0, on opening which water may be injected bya syringe or the like for cleansing the receptacle, such water flowing01? again through the Said openin Having now particularly described andascertained the nature of this invention and in what manner the same isto be performed,'I declare that what I claim is 1. Apparatus forcleansing fibrous materials consisting of a receptacle provided with asieve-bottom in combination with a stirring apparatus and a chain-bucketdevice which are alternately put in action.

2. Apparatus for cleansing fibrous materials consisting of a receptacleprovided with a sieve-bottom in combination with a stirring apparatusand a chain-bucket device, which is so arranged that a part of the chainis with out buckets, such part being situated within the receptacle atthe time when the stirring apparatus is being moved to and fro for thepurpose not to disturb the action of the latter.

3. In an apparatus for cleansing fibrous material, a receptacle for thematerial, a con veyer for removing the material from said receptacle, astirring device normally in the path of said conveyer, and means formoving said stirring device out of the path of said conveyer,

4. In an apparatus for cleaning fibrous ma terial, a receptacle providedwith a sieve-bottom, a conveyor for removing the fibrous material, astirrer-blade normally in the path of said conveyer, means forreciprocating said blade and means for raising and lowering said blade.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
